TENSION ROD FOR PREVENTING OVERTURN OF LADDER AND SLIPPING ACCIDENT
To solve the problem in which there is always risk for slipping and overturn as the ladder whose height is two times or more of user's height cannot be supported even by an outrigger underneath or human and there is no slipping prevention effect when an angle at which the ladder is laid against is not correct.SOLUTION: A correct angle is important for a ladder as it is too late after an overturn happens. A dislocation of an installation angle of the ladder should be eliminated. For this purpose, a set of left and right tension rods in the same length as the ladder are coupled to a high position of the ladder with a metal fixture, they support the ladder in an inverted V-shape so as to poke a tip of the ladder, the left and right parts are connected by adjusting a chain with a carabiner at a position to support both ends underneath at a correct interval to hold a correct position and angle, thus the overturn and a slipping can be prevented.SELECTED DRAWING: Figure 1
【課題】はしごには、滑りと倒れる危険性がいつもあります。長いはしごには下にあるアウトリガーや人が支えても人の２倍以上高いはしごではささえきれません。それに立てかける角度が適正でないと滑り防止効果はありません。【解決手段】はしごは適正な角度が大切です転倒してからでは間に合わない。はしごの設置角度をずれなくすれば良いのです。それにははしごと同じ長さの左右セットの突っ張り棒をはしごの高い位置に金具で繋ぎ、はしごの先端を突くようにハの字で支えてその下の両端を適正な間隔で支える位置で鎖をカラビナで調節して左右を繋ぐと適正な位置と角度がたもてるので転倒と滑りが防止出来る。【選択図】図１
